Roux was arguing his physical/mental condition for dimished capacity in mitigation only. Diminished capacity is not a defense under SA law. Now the mental health referral has put the defendant's condition potentially into the realm of a defense of pathological incapacity. Which is why the court said it was strange that the defense opposed it imo
Also, based on Vorster's testimony, the incapacity wouldn't only have to do with the mistake, but also with the response to a perceived intruder -- fight rather than flight.

And if the Judge doesn't accept that OP didn't know it was Reeva behind the door then the whole GAD issue is pretty irrelevant anyway. An argument of "Reeva made me really really angry and I reacted to this in an extreme fashion because I have GAD and therefore heightened responsiveness to threats to my reputation" doesn't really work, IMO.
(Karmaday - I just used your post to highlight a point I wanted to make, it wasn't specifically in response to you).
